Definitions

  • This invention relates to a selector lock in a gearshift device according to the preamble of claim 1.
  • Such a device is e.g. B. from DE-PS 30 00 577, Fig. 2, known, ball elements 7 cooperate with a cam 80.
  • the friction also only works with an adjustment, e.g. B. in a double H circuit from the Gasse 3/4 in the Gasse 5/6 and possibly still in the alley of the reverse gear.
  • an adjustment e.g. B. in a double H circuit from the Gasse 3/4 in the Gasse 5/6 and possibly still in the alley of the reverse gear.
  • the principle of this solution also enables a very simple and inexpensive design with reliable locking.
  • the locking of the reverse gear can also be included, for which separate locking elements 82 were required according to the prior art DE-PS 30 00 577, Fig. 4, 5.
  • the arrangement e.g. B. the alleys 3/4 and 5/6 as in a double H circuit on both sides of this locking ring a particularly cheap, simple and variable solution of the detent, since the design of the active surfaces on the detent, as well as on the nose of the locking lever , can be done according to the desired effect.
  • a rotary shaft 2 with a detent ring 3 and detents 32, 32A is mounted in the switch housing 4, the detent ring being connected to the rotary shaft via a clamping bolt 35.
  • a clamping bolt 35 Alternatively - dash-dotted and thinly drawn - detent rings 30 attached to the rotary shaft 2 can still be seen via Seeger rings 36.
  • two first bolts 5 are fastened to a respective bearing eye 41 of the switch housing 4 and each carry a locking lever 1 which can be pivoted radially about the first bolt 5 and is opposite, the lugs 11 of which have the detents 32, 32A or the detent rings 30 cooperate.
  • 41 are the bearing eyes on the switch housing 4 in which the bolts 5A are fastened.
  • the locking levers 1 are guided by the flat surfaces 42 of these bearing eyes and by sleeves 51 pushed onto the bolts 5, 5A, which can be directly or, as shown, over the heads support the bolt after installing the gearshift housing 4 on the gear housing 9.
  • the springs 6 are clamped between the switch housing 4 and the locking levers, these also having a guide 13 or contact surface 14 for the springs 6.
  • FIG. 3 also shows the arrangement of the locking lever 1 in the center of the rotary shaft 2 with the bolt 5, 5A arranged transversely thereto, which are supported on the transmission housing 9 on the transmission housing 9 as well as the known arrangement of the shackle spring 7 between the rotary shaft 2 and switch housing 4th
  • FIG. 4 shows schematically a section of a detent ring 3 fastened on a rotary shaft 2 with the representation of the alleys R / C, 1/2, 3/4, 5/6, 7/8, a double H circuit with the position of the nose 11 of the locking lever 1 in some streets.
  • the nose 11 is bound by the limitation of the pivoting movement of the locking lever 1 in the slot 12 by the bolt 5A (Fig. 1) so that there is a gap 81 in the radial direction between the collar of the detent track 33 and the nose and the system on the Detent 32, 32A occurs only on the active surfaces 34.
  • the fetter-spring package is set up and arranged so that the axial direction of action reverses in the axial direction when the nose 11 is positioned on the center of the detent 32, so that in the neutral position of the shift lever, this and thus the rotary shaft in the reduced area - Alleys R / C, 1/2, 3/4 remain in the alley 3/4 or are moved back to it without dialing power, while in the direct area - group gear 1: 1 - the stay in the alley 5/6 or the return from the Alley 7/8 takes place on this alley.
  • gear 1 1 - the stay in the alley 5/6 or the return from the Alley 7/8 takes place on this alley.
  • Latching forces from the spring 6 are only effective when the rotary shaft 2 is shifted from the Gasse 3/4 to the Gasse 5/6 and vice versa as well as when moving from the Gasse 1/2 into the R / C-Gasse.
  • the tied pivot position of the locking lever 1 radially inwards takes place when the spring 6 is preloaded.
  • the catches 32, 32A can also be arranged on the rotary shaft 2 —included — and incorporated — in other words — in one piece with it.
